RPA shields inherited DNA lesions for post-mitotic DNA synthesis
Single-stranded DNA during DNA replication and repair in S/G2 needs protection by replication protein A (RPA). Here the authors reveal that RPA also shields inherited single-stranded DNA in G1, representing replication remnants from the previous cell ...

The Nucleosome Remodeling and Deacetylation (NuRD) complex is a crucial regulator of cellular differentiation. Two members of the Methyl-CpG-binding domain (MBD) protein family, MBD2 and MBD3, are known to be integral, but mutually exclusive subunits of ...

Genome-wide maps of nucleolus interactions reveal distinct layers of repressive chromatin domains
Mapping nucleolar-associated domains (NADs) is challenging as the nucleolus is membrane-less. Here the authors adapted the DNA adenine methyltransferase identification (DamID) method by engineering a “nucleolar histone” that can mark genomic contacts ...

Triple-negative breast cancer (TNBC) is clinically defined by the absence of estrogen and progesterone receptors and the lack of membrane overexpression or gene amplification of receptor tyrosine kinase ErbB-2/HER2.

HSL1 and BAM1/2 impact epidermal cell development by sensing distinct signaling peptides
HAESA and HSL2 are receptors for IDA/IDL-family signaling peptides in plants. Here the authors show that HSL1, previously shown to recognize CLE9, preferentially binds IDA/IDL peptides and regulates leaf epidermal patterning independently of CLE peptides.

Vav proteins act as tyrosine phosphorylation-regulated guanosine nucleotide exchange factors for Rho GTPases and as molecular scaffolds. In mammals, this family of signaling proteins is composed of three members (Vav1, Vav2, Vav3) that work downstream of

Background Cancer-secreted exovesicles are important for cell-to-cell communication by altering cancer-related signalling pathways. Exovesicles-derived miRNAs (exomiRNAs)-target genes can be useful for diagnostic and prognostic purposes. Methods ExomiRNA

While cutaneous melanoma is linked to UV radiation, acral melanoma is not. Epigenetic mechanisms function as sensors to exposures and determinants of cell identity.

Plant responses to photoperiod [PDF]
Photoperiod controls many developmental responses in animals, plants and even fungi. The response to photoperiod has evolved because daylength is a reliable indicator of the time of year, enabling developmental events to be scheduled to coincide with ...
